Does any one have problem getting the same edge on the tip of the blade compared the the middle and end of the blade?

I've notice with my blade the foil obviously is raised up so while sharpening the tip to about 1" in I have problems holding the blade at the angle it was in when sharpening the middle.
I think it wouldn't be so bad if the base was bigger. I'm currently thinking of how I can make the base bigger so while sharpening the tip, the rest of the blade has a surface to site on and stay level.
